Question

I want to set two colors for UILabel's text. I tried TTTRegexAttributedLabel, but it is throwing unknown type error.

I tried following code too. But it is crashing at settext.

 NSMutableAttributedString *str = [[NSMutableAttributedString alloc] initWithString:@"Hello. That is a test attributed string."];
    [str addAttribute: @"Hello" value:[UIColor yellowColor] range:NSMakeRange(3,5)];
    [str addAttribute:@"That" value:[UIColor greenColor] range:NSMakeRange(10,7)];
    [str addAttribute:@"Hello" value:[UIFont fontWithName:@"HelveticaNeue-Bold" size:20.0] range:NSMakeRange(20, 10)];

[syncStatusLabel setText:(NSString *)str];

Is there any other way to set multiple colors for single UILabel text?

Answer 1

you can set text color with pattern image like bellow..

        [yourLable setTextColor:[UIColor colorWithPatternImage:[UIImage imageNamed:@"yourImageName"]]];

and also set different color with this bellow code.. please check tutorial with detail mate..

NSString *test = @"Hello. That is a test attributed string.";

 CFStringRef string =  (CFStringRef) test;
    CFMutableAttributedStringRef attrString = CFAttributedStringCreateMutable(kCFAllocatorDefault, 0);
    CFAttributedStringReplaceString (attrString,CFRangeMake(0, 0), string);



    /*
     Note: we could have created CFAttributedStringRef which is non mutable, then we would have to give all its
     attributes right when we create it. We can change them if we use mutable form of CFAttributeString.
     */



    //Lets choose the colors we want to have in our string
    CGColorRef _orange=[UIColor orangeColor].CGColor;
    CGColorRef _green=[UIColor greenColor].CGColor;
    CGColorRef _red=[UIColor redColor].CGColor;
    CGColorRef _blue=[UIColor blueColor].CGColor;    




    //Lets have our string with first 20 letters as orange
    //next 20 letters as green
    //next 20 as red
    //last remaining as blue
    CFAttributedStringSetAttribute(attrString, CFRangeMake(0, 20),kCTForegroundColorAttributeName, _orange);
    CFAttributedStringSetAttribute(attrString, CFRangeMake(20, 20),kCTForegroundColorAttributeName, _green);
    CFAttributedStringSetAttribute(attrString, CFRangeMake(40, 20),kCTForegroundColorAttributeName, _red);    
    CFAttributedStringSetAttribute(attrString, CFRangeMake(60, _stringLength-61),kCTForegroundColorAttributeName, _blue);
